CHURN'.

Specification of Letters Patent.

Patented Get. 5, 1969.

Application filed April 23, 1909. Serial No. 491,760.

To (LU whom it may concern.

Be it known that I, EDWARD A. FRANKLIN, a citizen of the United States, residing at Austin, in the county of Travis and State of Texas, have invented a new and useful Churn, of which the following is a specification.

' This invention relates to churns and more particularly to dashers for use in connection therewith.

T he object of the invention is to provide a churn dasher of that type designed to retate, the said dasher consisting of radially extending blades so shaped and located as to force the milk or cream both upwardly and downwardly during the rotation of the dasher in one direction thus greatly facilitating the formation of butter and materially decreasing the labor incident to the operation of the churn.

With these and other objects in view the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims.

In the accompanying drawings, the preferred form of the invention has been shown.

In said drawings, Figure 1 is a perspective view of a complete churn embodying the present improvement, a portion of the churn body being broken away. Fig. 2 is a plan view of the dasher in connection with the churn. Fig. 3 is a transverse section therethrough.

Referring to the figures by characters of reference 1 designates a base having standards 2 thereon connected by a cross-head 3 from which hangers at depend. A shaft 5 is journaled within one of these hangers and also within one of the standards 2 and carrie's a gear 6 which receives motion from a drive gear 7 connected to a shaft 8 which is journaled in one of the standards 2 and is designed to be actuated in any preferred manner as by means of a crank 9. A bevel gear 10 is also secured to the shaft 5 and meshes with the smaller gear 11 secured to a shaft 12, the upper end of said shaft being journaled' within the cross-head 3 while the lower end thereof may bear within the churn body.

The dasher constituting the main portion of the present invention consists of a sleeve 13 designed to receive the shaft 12 and to be secured to it in any preferred manner as by means of a set screw 141. This sleeve has blades 15 extending radially therefrom, the advancing edges of the blades being convexed as shown at 16 while the opposed edges of the said blades are concaved as indicated at 17, the two edges of each blade gradually d'verging from the central portion of the dasher and then gradually converging along curved lines extending in a direction opposite to that in which the dasher is designed to be rotated. Said converging edges 16 and 17 form wings 18 and, as indicated in Fig. 3, each blade is twisted so as to cause its wing 18 to incline upwardly toward its free end. Each blade is also inclined transversely at its center so as to bring the advancing edge 16 above the opposite edge 17, the middle portion of the blade thus presenting an inclined face designed, when the dasher is rotated, to direct downwardly that portion of thediqnid contents of the churn located in the path thereof. The blades 15 are surrounded by a cylinder 19 which is open at both ends and is concentric with the sleeve 13, the wings 18 being secured in any preferred manner to the inner surface of the cylinder. As shown in Fig. 3 the cylinder may be reinforced at its ends by means of ribs formed by folding the edges of the cylinder backward, these reinforcing ribs being indicated at 20.

In using the churn herein described the cream is placed within the churn receptacle 21 which is located on the base 1 between the standards 2 and the shaft 12 is rotated by means of the gears 7, (3 and 10. The dasher will thus be caused to revolve in the direction indicated by the arrow in Fig. 2 and the elevated advancing edges 16 of the blades 15 will operate to force the liquid downwardly while the upwardly inclined wings 18 will tend at the same time to throw the liquid in the path thereof upwardly. A violent beating action is thus produced because of the simultaneous movement of the liquid contents in reverse directions, such movement being produced by each blade of the churn dasher. It will be apparent therefore that the globules will be quickly broken up and the formation of butter thus greatly facilitated.

It is to be understood of course that various changes may be made in the construction and arrangement of the parts without departing from the spirit or sacrificing the advantages of the invention.

\Vhat is claimed is 1. A churn dasher including a shaft engaging member, and blades radiating therefrom, each blade being twisted to simultaneously direct in opposite directions the liquid in the path thereof and an annular connection between the outer terminals of the blade.

2. A churn dasher including a shaft e11- gaging member, twisted blades radiating therefrom, each blade having its intermediate and outer end portions inclined forwardly in opposite directions and a ring connecting the outer ends of the blades and extending above and below said blades.

A churn dasher including a shaft engaging member, blades radiating therefrom, each blade having an inclined intermediate portion and a wing at the outer end of said blade and inclined oppositely to said intermediate portion, and a cylindrical connection between the outer ends of the blades and extending above and below said blades.

f. A churn dasher including shaft engaging means, transversely twisted blades eX- tending radially therefrom, each blade constituting means for simultaneously forcing liquid in opposite directions, and a tubular cylindrical connect-ion between, and extending above and below, the outer ends of the blades.

5. A churn dasher having shaft engaging means, transversely twisted blades eXtending radially therefrom and each blade constituting means for simultaneously forcing liquid in opposite directions when the dasher is rotated in one direction, and a connection between the outer ends of the blades.

6. A churn dasher including a tubular member, radially extending blades thereon having curved edges each blade having a terminal wing inclined upwardly in a direction opposite to that in which the blade rotates, each blade being twisted transversely with its advancing edge above the opposite edge thereof.

7. A churn dasher including a tubular member, radially extending blades thereon having curved edges each blade having a terminal wing inclined upwardly in a direction opposite to that in which the blade rotates, each blade being twisted transversely with its advancing edge above the opposite edge thereof, and a cylindrical connection between the wings of the blades.

8. A churn dasher including a shaft engaging member and twisted blades radiating therefrom and each having a terminal wing inclined upwardly in a direction opposite to that in which the blade rotates, the intermediate portion of the blade being inclined downwardly in the direction in which the blade rotates and the advancing edge of the blade being convex, there being suflicient space between the blades to permit the passage of liquid directed upwardly from the path of the intermediate portions of the blades, and a cylindrical tubular connection between the outer ends of the blades and eX- tending above and below said blades.

9. A churn dasher including a shaft engaging member and blades radiating therefrom and each blade being twisted in opposite directions at its center and at one end thereof respectively, the advancing edge of the blade being convex in the direction of its length and a cylindrical connection between the outer ends of the blades and con centric with the shaft-engaging member.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
